Depending on the main driver of your knee condition a high proportion of the discomfort and pain from your arthritis could be coming from inflammation of the knee joint capsule and the fluid produced, not just joint wear.
Arthrosamid® is a revolutionary hydrogel treatment designed to reduce or stop inflammation which addresses this pain source and delays wear. This is as inflammation can degrade a joint directly or indirectly through loss of strength and therefore stability.
Its unique composition ensures it remains effective long-term, providing lasting relief from joint discomfort in a single injection. Dubbed by one patient the ‘liquid knee replacement’ due to its longevity with current research showing 5 years (limited only by the length of the trial so far) and recipients having lasted much longer.
Rediscover a pain-free, active lifestyle with Arthrosamid®.
The injection is precisely administered into the knee joint using ultrasound guidance for maximum accuracy, ensuring the hydrogel is delivered to the exact spot so it can find its home in the capsule of the knee.
Arthrosamid® is absorbed into the capsule where, as non-biodegradable, it remains to blocks inflammation from occuring. This results in pain relief, ablity to use the knee and stay strong and thus delay wear. Unlike temporary treatments, the hydrogel stays in the joint to provide consistent relief for years.
Arthritis can be driven in a number of ways i.e. trauma, or a bias towards either bone degradation or inflammation of the joint. Each knee will be driven differently and at a different stage of wear.
Every patient is different with regards to such factors as to stage of life to have a replacement, ability to have a replacement, finances and applicability for the injection.
Having attended a user group meeting in Denmark at the Contura factory, having completed the procedure over 20 times and with the ability to review the knee on ultrasound Mark is an expert in patient selection and this consultation is crucial to help you consider what result you could expect from the injection.
Prophylactic antibiotics are required to be taken 1-2 hours prior to your injection. Your current symptoms and mobility levels will be recorded, if not already. The procedure itself takes approximately 30 minutes per knee and is performed under ultrasound guidance for accuracy and help draining the knee if required. A single needle is used to administer local anesthetic and 6ml of Arthrosamid.
Your knee might feel ‘tight , cushioned, full, a bit pressured’. The local anaesthetics will last for approx three hours so you will be pain free. Details of a knee rehab programme are discussed. it is recommend someone else drive you home however most patients are self sufficient.
After the procedure, you are advised to rest for 72 hours.
What will it feel like after the injection?
The body. takes time to recognise the foreign substance is not a threat and and to absorb / accept the hydrogel – So for the first 6 weeks you may experience some pain/more pain and discomfort.
This is due to:
Post injection flare: Injection-related mild to moderate pain and/or mild swelling during the first few days to weeks following the injection may occur or increased swelling of Baker’s cyst present may also occur
When will I begin to feel less pain?
It can take four to twelve weeks to feel the maximum benefit. Clinical data
shows that most patients start to feel an effect within a few weeks.
Early responder = 1-6 Weeks
Typical Responder = 6-12 weeks
Delayed Responder = 3M – 6M
Not all patients respond at the same rate and achieve the same reduction in pain
When can I go back to normal activity?
48H reduce activity/rest
First 2 weeks normal ADLs;
As with any invasive joint procedure, it is recommended to avoid strenuous activity (e.g. tennis, jogging or long walks) during the first few weeks after the injection and begin rehabilitation activities when possible.
Our team is always available to address your concerns and guide you through your recovery journey.
For any unforeseen circumstances and safety it is recommend someone else drive you home however most patients are self sufficient.
Say goodbye to multiple injections and constant treatments. One single Arthrosamid® injection delivers long-term relief, reducing the need for frequent visits.
Unlike surgery, Arthrosamid® requires no recovery time. The injection is minimally invasive, and patients typically return to their regular activities immediately after the procedure.
Clinical studies show that Arthrosamid® significantly reduces pain within the first four weeks, with results lasting 5 years. Patients experience sustained improvement in joint function and mobility.
Arthrosamid® has been rigorously tested for safety and biocompatibility. Its hydrogel formulation integrates seamlessly with the body’s tissues, ensuring a safe and reliable treatment with minimal risk of adverse reactions.
To ensure precise delivery, the injection is performed using ultrasound technology, allowing for pinpoint accuracy and greater safety in targeting the affected area.
Over 80% of patients report noticeable improvements after one year. The younger and less worn the better the result overall.
WOMAC pain scores show results at twice the minimally clinically significant difference (MCID) showing strong meaningful change to a patient
These results are proven up to 5 years with this being the length of the trial, with many patients already having many more years than this.
After the injection, we recommend avoiding strenuous activities and resting the knee for approx 72 hours to minimise the risk of inflammation or flare-up following your procedure.
A gradual return to previous activity level is then advised.
Typically, the benefit from the injection begins around four weeks after the injection, majority of benefit observed around the 12-week mark full and full potential can take at 6 months.

“There was a little soreness and stiffness in the knees for the first 24 hours, but considerably less than what I expected. My knee joints feel a lot better, as if cushioned. You did a really great job. Much appreciated.”
– Glenn Davis, Accounting Lecturer & Avid Cyclist
Joints like the shoulder bursae or hip require precision to ensure the injection hits the target. Ultrasound ensures the needle is accurately placed.
Some joints and tendons, such as the hip joint or hamstring tendon, are too deep to reach without guidance.
POCUS helps to distinguish between conditions like Achilles tendinopathy and retrocalcaneal bursitis, ensuring the correct treatment is provided.
Arthrosamid is an innovative, non-biodegradable hydrogel injection designed to provide long-lasting pain relief for knee osteoarthritis. It works by integrating into the synovial tissue, reducing inflammation in the joint helping it to be as pain free as possible and stay strong and stable delaying wear.
The gel absorbs into the joint capsule and the magic bit is the make up of the gel is similar to the bodies cells in that area so the body doesn’t reject, allows it to sit one cell layer deep, and being non-biodegradable it stays there.
It then helps return the thickness and regularity to the knee capsule lining and prevents inflammatory cells communicating all of this leads to less inflammation in the joint. This helps to restore mobility and provide significant, long-lasting pain relief for osteoarthritis sufferers.
Clinical studies have demonstrated that Arthrosamid provides substantial pain reduction and improved knee function for osteoarthritis patients. Unlike steroid injections, which offer temporary relief, Arthrosamid is designed to provide long-term benefits with fewer side effects.
Arthrosamid is ideal for individuals with inflammatory led knee osteoarthritis who are looking for long-term pain relief without surgery. There are many factors that will determine your suitability such as your age, grade of arthritis, applicability to surgery. Mark at Rebound physio has been part of user group meetings in Denmark at the Contura factory and is a specialist in patient selection and can guide you as to how you might benefit.
Arthrosamid injections are provided by specialists in musculoskeletal medicine. You will typically require an initial assessment to determine your suitability before receiving the injection at a clinic offering ultrasound-guided procedures.
Most patients experience little to no downtime after the injection. You may feel slight discomfort for a few days, but normal activities can typically be resumed shortly. Full pain relief benefits are often noticeable within weeks.
Arthrosamid is well-tolerated, but some patients may experience mild swelling, stiffness, or temporary discomfort at the injection site. Serious side effects are rare, and no allergic reactions have been recorded.
Studies suggest that a single Arthrosamid injection can provide pain relief for up to 5 years, making it one of the longest-lasting injectable treatments for knee osteoarthritis.
Patients can slowly resume their normal low impact daily activities approximately 72 hours post injection.
However with any invasive joint procedure, it is recommended to avoid strenuous activity (e.g. tennis, jogging or long walks) during the first few weeks after the injection and begin rehabilitation activities when possible.

EXCELLENT Based on 132 reviews Rose Floyd2025-02-16Trustindex verifies that the original source of the review is Google. Mark was very informative at the consultation, and didn’t rush me into the injections. I went back 7/10 days later and it’s now been a fortnight since they went in. Previously I had pain daily and couldn’t walk very far. I am now enjoying being pain free Hannah-May Elmasry2025-02-11Trustindex verifies that the original source of the review is Google. Really knowledgeable and friendly physio, fully assess and explains things thoroughly would highly recommend andy muir2025-01-30Trustindex verifies that the original source of the review is Google. Mark is a wonderful knowledgeable practitioner, he explains things perfectly. I had hip steroid and hyaluronic injections and are feeling the benefits already. I would highly recommend Mark to anyone. Rebecca Benson2025-01-27Trustindex verifies that the original source of the review is Google. Worth his weight in gold. This guy has been a godsend to me. After experiencing extreme levels of pain for three weeks with whiplash after a car accident.. I’d tried another physio as well as attending my GP several times for medication and nothing had touched me. I was becoming depressed with the level of pain I was experiencing… Mark did an extremely thorough consultation, talked me through options and got to work. After my first session I felt some relief, though the benefits continued throughout the day; That evening was the first evening I didn’t have vice crushing headaches from moving my neck downwards and that night was the first night I hadn’t woken up in the middle of the night needing to take pain medication. The following day he did more work on the front of my neck and I practically floated out of the place. I really can’t recommend him enough. For the first time in three weeks I see some light at the end of the tunnel. I’d never experienced pain like it before, but he’s really made such a difference in such a short space of time. Professional, experienced and a lovely person. Thank you so much. Robert Serkis2025-01-10Trustindex verifies that the original source of the review is Google. Highly recommend seeing Mark Boundy I had very bad hip problem which had lasted a year Mark administered a cortisone and lubricant injection 10 months ago the pain eased very quickly and it's improved to where I don't have a problem darren ross2025-01-04Trustindex verifies that the original source of the review is Google. Booked in to see Mark regarding a hip/glute issue. Following an initial consultation I booked a dry needle appointment (which he managed to get in the same day for me) provided immediate relief to the issue. Was prescribed some exercises and stretching to help moving forward. Great service, reasonably priced and provided clear answers to all my questions. Good to know I have a reliable option for any future problems Wayne Price2024-12-14Trustindex verifies that the original source of the review is Google. Shoulder pain for a long time got unbearable. And literally 1 visit and within 3 days pain free Debbie Tasker2024-12-05Trustindex verifies that the original source of the review is Google. Finding Mark has been life changing, I have had years of back problems since the birth of my second child, After over doing it at the gym, I was in terrible pain and discomfort, a feeling I deal with often, We found Mark, so friendly, helpful, and extremely knowledgeable, he was able to help me with dry needling, which made a huge difference to my ability to move better, along with physio which was intense but so amazing, moving forward to where I am today! After feeling so broken for so long, I see the light at the end of the tunnel all thanks to Mark 🙏🏻 Forever grateful. Thank you 🙏🏻 Emma Wheat2024-11-11Trustindex verifies that the original source of the review is Google. Mark was recommended to my hubby who was suffering with a very bad knee. Lots of pain when walking/bending and very swollen. I dropped him off to have his knee assessed, he was impressed with the ultrasound scan Mark did (got alot more information about the state of his knee after 15 minutes with Mark than after an MRI with NHS!). Steroid & thick oil were given as an option as the knee was a bit of a mess, osteoarthritis and cartilage torn. Mark offered no guarantee but it was deemed worth a try. It was the right decision. 3 weeks in and there is no pain - used to be constant pain. Less discomfort - used to ache. No swelling. The result is he can now walk & kneel down better than he has in about 20 years. Lesley2024-10-14Trustindex verifies that the original source of the review is Google. I can’t rate Mark highly enough. I previously visited him a few years ago for Achilles heel pain and swelling which he swiftly assessed was related to issues in my hip and after a few sessions he resolved my issue. When I had pain in the ball of my foot recently, I visited him again after the NHS were unhelpful. Mark immediately knew that I was suffering with Mortons neuroma for which he administered a steroid injection guided by ultrasound. It’s very clear that Mark is very skilled and knowledgeable in his field, he also makes you feel very at ease and explains the whole treatment process carefully. Even though Mortons neuroma tends not to go away completely I am now almost pain free following the treatment. I would highly recommend Mark to others.

After completing a Biology BSc, my journey in physiotherapy began in 2004 at King’s College, London. I spent eight years in the NHS, where I saw how long waiting lists and short appointments hindered effective rehabilitation. This led me to pursue an MSc in Manual Therapy in 2015, becoming a member of the MACP.
I moved into private practice at Oxford Sports Physio & Pilates, where I helped rehabilitate high-level athletes, including GB rowers and Oxford University sports teams. Today, I’m an expert generalist with a passion for treating a variety of musculoskeletal issues.
While I don’t specialize in one area, I have a keen interest in using MRI machine for diagnostics and injection therapy, which allows me to offer precise, effective treatments. Combined with medication prescription, I provide a comprehensive range of musculoskeletal care.
